Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid used for a rain gutter of each home, a rain catch catcher for collecting rain water from the ground surface, or the like, and a rain water basin for intensively flowing rain water.

[0002]

2. Description of the Related Art Conventionally, as a cover for a rainwater basin of this type, a structure is used in which a relatively large slot is opened for a handle and for ingress of rainwater. Invades the inside of the box, and flows out downstream through the mud pool at the bottom of the box.

[0003]

[Problem to be Solved by the Invention] However, since the rainwater basin lid has a structure in which a long hole is opened, insects such as mosquitoes enter the mud reservoir of the basin from this long hole. In some cases, swelling may occur, resulting in an unsanitary condition.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cover for a rainwater basin which can prevent invasion of insects and the like and maintain good environmental hygiene.

[0005]

According to a first aspect of the present invention, there is provided a rainwater basin lid that is openably and closably fitted to an upper opening of the rainwater basin, the lid body having a water-permeable hole. upon
A net body is provided on the same surface as the upper surface of the lid body .

[0006]

[Action] In rainwater桝用lid devised according to claim 1, wherein the entry into the lid body of permeable pores of such insects in net member provided on the upper surface of the lid body and entering the rainwater桝内prevention So that
Environmental hygiene can be maintained satisfactorily without generating bubbling in the rainwater basin. Further, since there is provided a net member on the upper surface and coplanar closure body, it can be easily removed sediment accumulated on the lid in such broom and hand. Therefore, good water permeability can be maintained without reducing the water permeable area of the lid.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the rainwater basin lid of the present invention will be described below with reference to the drawings.

1 to 4, reference numeral 1 denotes a rainwater basin 2
A rainwater basin lid that is openably and closably fitted to the upper opening of FIG. 1 and has a diameter of, for example, 200 mm or less. The lid body 3 of the lid 1 is molded from a synthetic resin such as vinyl chloride. , A large number of water permeable holes 4 penetrating vertically.

Reference numeral 5 denotes a net formed of synthetic resin or metal. The net 5 is provided on the upper surface of the lid body 3 so as to cover the water permeable hole 4 and is flush with the upper surface . . That is, the bent outer edge 5a of the net body 5 is insert-molded above the outer edge 3a of the lid body 3 so that the upper surface of the net body 5 is flush with the upper surface of the outer edge 3a of the lid body 3, Further, as shown in FIG. 3, the net body 5 is pressed from above by a plurality of bosses 6. FIG. 5 is a sectional view of the net body 5.

The size of the mesh of the net body 5 is as follows.
It must be greater to the extent that insects do not occur and by clogging small and sand to an extent which can not pass such mosquitoes, for example, formed Messi Interview extent.

The outer edge 3a of the lid body 3 is formed with a pair of notches 7 for grips at the upper part, and an annular concave part 9 into which an elastic ring 8 is fitted. Have been.

In FIG. 1, reference numeral 11 denotes a basin body of the rainwater basin 2, and the basin body 11 is formed of synthetic resin, and formed with openings 12 and 13 having enlarged diameters at upper and lower parts, respectively. One outlet 14 and three inlets 15 (right side in FIG. 1), an inlet 16 (front side in FIG. 1), and an inlet 17 (rear side in FIG. 1) protrude substantially orthogonally. Have been.

Reference numerals 18 and 19 denote height adjusting pipes made of synthetic resin fitted to the receiving ports 12 and 13, respectively.
Has a bottom closed with a closure 20 and a mud reservoir 21 inside.
Are formed.

Reference numeral 22 denotes a lid receiving member fitted on the upper portion of the height adjusting tube 18. The lid receiving member 22 is formed of synthetic resin, and the lid 1 is openably and closably formed on the upper inner periphery. A lid receiving step 23 to be fitted is formed.

Numeral 24 denotes a mud reservoir that is removably disposed in the mud reservoir 21 of the basin body 11. The mud reservoir 24 is formed of a synthetic resin, has a substantially cylindrical shape, and has a closed bottom. A handle 25 is provided at the upper part.

Next, the operation of this embodiment will be described.

First, as shown in FIG. 1, the rainwater basin 2 having the above structure is installed at the installation site without the lid 1 and the mud reservoir 24 being provided, and the three inlets 15, 16 and 17 are provided. An upstream pipe (not shown) is connected to a necessary portion of the pipe, an unused portion is closed with a cap (not shown), and a downstream pipe (not shown) is connected to the outlet 14. .

Next, the user holds the handle 25 and inserts the mud reservoir 24 from above the height adjusting pipe 18, and arranges the mud reservoir 24 in the mud reservoir 21. Next, after the elastic ring 8 is fitted into the annular concave portion 9 of the cover 1, the cover 1 is fitted to the lid receiving step 23.

Then, drainage such as rainwater containing earth and sand flows through the upstream pipe, the net body 5 and the water-permeable hole 4 of the lid 1, and flows into the mud reservoir 24 at the lower part of the rainwater tub 2. At the bottom of the storage container 24, soil and the like are deposited to form a muddy sediment, and the supernatant drainage flows out of the outlet 14 to the downstream side. When the sediment has accumulated in the mud reservoir 24, the lid 1 is opened, the handle 25 is taken out of the mud reservoir 24, the sediment is discarded, and the sediment is disposed at the original position.

[0020] Then, penetration of at net member 5 provided in the upper surface of the lid body 3 to the permeable hole 4 of the lid body 3, such as insects is prevented, thus the penetration of rainwater Masuichi 2 of such insects As it is prevented, there is no bubbling in the rainwater basin 2,
Good environmental health can be maintained.

Further, since the net member 5 is provided on the coplanar with the upper surface of the lid main body 3, by one wipe sediment deposited on the upper surface of the lid 1, such as hand or broom, the easy removal be able to. Therefore, without water penetration area of the lid 1 is reduced, Ru can satisfactorily maintain permeability.

[0022] In addition, this the nets body 5 on the top surface of the lid body 3
The outer edge 3a of the lid body 3 is bent in a state where the outer edge 5a of the net
To prevent the net body 5 from falling off.

[0023] In the above embodiment has been described net member 5 having the shape shown in FIGS. 1 to 5, the present invention is not limited thereto, for example, the outer edge portion 5c as shown in FIG. 6 at right angles bending or, or a further folding the tip portion 5e of the outer edge portion 5d as shown in FIG. 7 may take a variety of shapes. Further, as shown in FIG. 8 , a metal reinforcing member 27 is arranged, for example, in a cross shape below the metal net member 5, and the reinforcing member 27 is attached to the net member 5 by spot welding. The strength of the body 5 can be improved.

The structure of the rainwater basin 2 to which the cover 1 of the present invention is fitted is not limited to the structure shown in FIG.
The lid 1 of the present invention can be used in rainwater basins having various structures such as a structure in which one inlet or two inlets are provided in various angular directions or a structure in which no inlet is provided.

[0025]

[Effect of the invention] According to the invention of claim 1, wherein penetration and invasion of rainwater桝内to cover the body of the permeable pores in such insects in net member provided on <br/> upper surface of the cover body Therefore, environmental hygiene can be maintained satisfactorily without the occurrence of swelling in the rainwater basin. Further, the net member so provided on the upper surface and coplanar lid body, the accumulated sediment on rainwater桝用lid can be easily removed by such broom and hand. Therefore, good water permeability can be maintained without reducing the water permeable area of the lid.
